I have had broadboand since 2000 and in that time I have nothing but problems with download speeds. Prior to having access to adsl2 and the installation of a road side cabinet around the corner speeds on average were less than 100 KB/s. Even now when starting a download they may start 500-600 KB/s then drop away. I have talked with various help desks over the years but still no joy. I have attached screen shots of my modem settings, status and speedtest results.

I have a gut feeling that somehow my connection is defaulting back to adsl1 ( if at all possible ). The reason I say this is because the three modems I have can only connect to the net when set to auto. Setting to adsl, adsl2 or adsl2 + will end with no connection. The new Technicolor from extra will not work full stop, as it does not have an auto mode setting under DSL mode. Our house was built in 1992 so it is possible there is a wiring fault. The house is not fitted with a master splitter. Of course none of this makes sense to me when my line attenuation is as shown in attachments.

If someone is able to steer me in the right direction it would be appreciated.

To me it looks like you've been provisioned on a special profile for whatever reason from a long time 5+ years ago back in the ASAM/ADSL1 days. Since then you have been migrated to ISAM and ADSL2+ however you are not on one of the standard profiles. Your port will need to be reset onto one of the ISAM ADSL2+ profiles. You may also need to be moved from BUBA to EUBA if your line is capable.Have you ever called your previous ISP Xnet over the past 5+ years about line/connection issues?

I have been with 4 ISP's over the years. I have raised this issue with them all, they run checks and tell me alls well. Even when I changed in August last year I made sure I was going to get full download speed before the switch. I started complaining in September.

Over the years I have had 5 different modems. All connected in the same manner using the settings from the isp, user name & password, no tinkering. Have tried the Technicolor modem, reset it and it sits there blinking. The interface message reads " connection could not be established. Could not bring up link. The other message is Your dsl connection is down.

I have now had a chance to do the isolation test. Before the test I took readings from the modem and ran a speedtest from 2 different servers. I have unplugged the 2 phones we have and filters then plugged the modem direct to jack point. I tried the jack I usually hook the modem to, then the jack which is first in line.

I have attached the fresh screenshots for the modem and new speedtest.net results. The two bottom test are my normal setup, the top 4 are the isolation test from the two jacks. I see no difference at all. Back to the drawing board.

DSL Type: non.shdsl.opermode adsl.t1.413, line.type.pots, latency.interleaved. What does all this mean?
